There has been an interest by many companies and environmental groups in the past decade in developing a biodegradable plastic to be used for foodservice products. While on the surface this appears to be a solution to littering and other disposal issues, some researchers feel these products actually may pose environmental risks that outweigh any benefit.
According to a report commissioned by Australian Department of the Environment and Heritage, potential adverse effects include:
| 1. | Oxygen depletion in waterways due to the breakdown of starch-based plastics |
| 2. | Ground and water pollution due to by-product degradation (additives and modifiers) |
| 3. | Slow or partial degradation that could be harmful to marine life |
| 4. | Unacceptably high organic or metal contamination derived from biodegradable residuals affecting soil and crop degradation when present in compost |
| 5. | An increase in litter since quick breakdown and disappearance will be the expectation of the public |
| 6. | A decline in existing plastics recycling programs |
Also, according to the Environment and Plastics Industry Council (Canada) and the Biodegradable Products Institute (U.S.) , biodegradable plastics do not break down in landfill conditions. |
